i do quite a bit of veneering and if i use commercial veneer or thinly cut homemade veneer (maybe trying to stretch materials or my bandsaw wasn't tuned), i've been getting wrinkling in my veneer.
i beleive the other aspect is the amount of glue i'm using. i think that hydraulic pressure builds up and the excess has nowhere to go so it pools, exacerbating the amount of glue issue in places. then combine that with thin materials, it becomes soaked and i get wrinkles.
i guess this turned into an advice post - if you are using thin veneers, be judicious with the glue, especially in the middle of the panel. around the edges, add an extra bead. on the but in the middle, just enough to cover.
if you use a roller, try rolling out the excess from the roller before adding new glue.
